HOSE-COUPLING IMPLEMENT.

Specification of Letters Patent.

Patented Aug. 22, 1911.

Application filed November 1, 1910. Serial No. 590,189.

To all whom it may concern:

Be it known that I, DAN D. STRONG, citizen of the United States,residing at Mom: phis, in the county of Shelby and State of Tennessee,have invented certain new and useful Improvements in Hose-CouplingImplements, of which the following 1s a specifi 'ation.

This invention relates to improvements in implements for applying hosecouplings, and has for one of its objects to improve the constructionand increase the e'l'licieney and strength of devices of this character.

Another object of the invention is to provide a device of this characterespecially designed for applying wire coupling dc: vices and tomaterially increase the grip of the coupling devices upon the hose.

With these and other objects in view the invention consists in certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claim; and, in the drawingsillustrative of the preferred embodiment of the invention, Figure 1 is aside elevation of the improved implement applied, with the parts intheir first position; lfig. is a plan view of the same; Fig. 3 is a simlar view of the improved implement, showmg the positions of the partsafter the strain has been applied; Fig. 4 is a longitudinal sectionalview; Fig. 5 is a longitudinal sectional view of the body with the partsdetached, illustrating the interior construction; Fig. 6 an endelevation.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters. a

The improved device comprises a body 10 internally threaded at one end,as shown at 11., and with an internal guideway 12 near the opposite endand with longitudinal bearing shoulders 13 in the sides of the guideway.The body 10 is likewise provided with upwardly directed sides oppositethe guideway 12 and the shoulders 13, as shown at 141 and with anopening between the sides communicating with the guideway. Fittingbetween the sides 1-1 of the body is a clamp lever 15, the clamp leverbeing pivoted at 16 between the sides. At its shorter end the lever isprovided with a recess 17 corresponding in shape to the guideway 12 andwith the portions opposite the guideway roughened, as indicated at 18,and designed to operate above the shoulders 121 and clamp the legportions of the wire clamp upon the shoulders, as hereafter explained.At its longer end the lever 15 is provided with a tlnreaded aperture toreceive apressure imparting screw 20, the inner end of the screw bearingupon the body 1.0, as shown. By this simple means the grip portions 18of the lever may be firmly clamped against the wires and hold them uponthe shoulders 13.

Slidably disposed in the guideway 12 and likewise extending into therecess 17 of the lever 15 is a piston member 21, the piston member 2.].being preferably square, while the guidcway 1,2 and the recess 17 arelikewise square, so that the member 91 may be moved longitiulinally ofthe body, and held from rotation. At its outer end the piston member 21is provided with a notch 22 to receive the bight portion of the wire, ashermfter explained. At its inner end the member 21. is connected by aswivel joint 23 to an operating srrcw 24-, the operating screw beingthreaded into an externally threaded nut 25, the nut being arranged toengage in the thrcmled portion 11 of the body. The screw 21 is providedwith an operating hand wheel 26 at its outer end. By this means it willbe obvious that the member 21 may be forcibly actuated by simplyrotating the wheel 26. The threads of the screw 2-1 are preferablycoarse, and the screw will be large cmmgh to enable the requisite gripto be applied when the couplings are attached to the hose.

\Vith an implement thus described the operation as follows: The wire isfurnished in the shape shown in Fig. 7 and prior to the application ofthe implement it is mam'lally or othemvise bent around the hose,indicated at 27 and the terminals Q82) inserted beneath the bightportion 230 of the wire, or in the position shown in l*igs. 1 and 2. Theterminals 28--29 are then inserted into the space between the shoulders13 of the body 10 and the grip faces 18 of the lever 15 with the bightportion 30 of the wire engaged by the notch 22 of the member 21. Thescrew 20 is then o r erated to firmly clamp the side portions of thewire upon the shoulders 13 and thus firmly couple the same to the body.The screw 21- is then actuated by the hand wheel 26 to force the member21 through the guideway 12 and thus force the wire around the hose, andembed the same into the soft yieldable hose material. The pressure canbe continued as long as required, or until the requisite tension hasbeen secured when the body is rotated around the bight portion 30 as acenter, or disposed in the position shown in Fig. 3, which movementbends the terminals of the leg portions of the wire around the bightportion and thus completes the coupling action. It will be obvious thatany required pressure may be applied through the action of the powerfulscrew 24, and all leakage between the hose and the tube upon which it iscoupled eifectually prevented.

The improved implement may be employed in connection with hose ofvarious sizes and to hose employed for various purposes, but theimproved implement is designed more particularly for uniting the hose topipes in air brake apparatus, and where an abnormal resistance isrequired.

The improved implement is simple in construction, can be inexpensivelymanufactured, is strong and durable, and enables the operator to apply avery strong grip upon the coupling devices.

The implement may be manufactured in different sizes.

Having thus described my invention, what is claimed as new is:

An implement of the class describedcomprising a tubular stock, havinglongitudinal guideways at one end and internally threaded at the otherend, a threaded bushing engaging in the threaded terminal of the stock,a clamping device carried by said stock, a piston member operating insaid guideway, said clamping device being adapted to engage theterminals and said piston adapted to engage the bight portion of a Ushaped wire, a screw engaging through said bushing, and a swivel deviceconnecting said screw to said piston whereby said clamping device andpiston co-act to cause the wire to be bent around a hose.

In testimony whereof, I afliX my signa' ture in presence of twowitnesses.
